Abstract

An automated initial program load (IPL) and standard time of day (TOD) via an IBM Personal Computer (PC) establishes the centralized computer operations project (CCOP), that has as its goal the introduction of an unattended/automated data processing center operation. This innovation minimizes the operator staff size, allows synchronization of system clocks, and permits the operation of remote systems that are unattended by emulating the functions of the IBM 3278 Model 2A terminal. This terminal, directly wired to the central processing unit (CPU) of such machines as the IBM 3081 and IBM 4300 series machines, permits an operator to initial microcode load (IML), initial program load (IPL), set the time of day (TOD) clock, start and stop the CPU, and several other functions.

Automated IPL and Standard Time of Day Via IBM Personal Computer

An automated initial program load (IPL) and standard time of day (TOD) via an IBM Personal Computer (PC) establishes the centralized computer operations project (CCOP), that has as its goal the introduction of an unattended/automated data processing center operation. This innovation minimizes the operator staff size, allows synchronization of system clocks, and permits the operation of remote systems that are unattended by emulating the functions of the IBM 3278 Model 2A terminal. This terminal, directly wired to the central processing unit (CPU) of such machines as the IBM 3081 and IBM 4300 series machines, permits an operator to initial microcode load (IML), initial program load (IPL), set the time of day (TOD) clock, start and stop the CPU, and several other functions. A function of the CCOP implementation is the automatic control of these operator actions that achieves this capability via the use of the IBM PC instead of the IBM 3278 Model 2A terminal. The input/output (I/O) port 2 permits the IBM PC 5 to appear as a conventional IBM 3278 Model 2 to Host 1. I/O port 3 via a suitable communications link provides a path to the CCOP master machine 6. I/O port 4 contains suitable hardware to emulate the special keys and lights of a conventional 3278 Model 2A. A master control program in IBM PC 5 provides the necessary mechanism to control items 2, 3, and 4. In operation, the CCOP master machine 6, e...
